drm/xe/trace: Print device_id in xe_trace_guc events

Browse Source 
In multi-gpu environments it is important to know the device
guc txn belongs to. The tracing information includes the device_id
to indicate the device the event is associated with.

v2: Use variable sized variant to display dev name(Gustavo)
v3: Pass single argument to __assign_str to fix kunit error
v4: Minor formatting tweaks
